Supporting responsive parenting in real-world implementation: minimal effective dose of the Video Interaction Project.

Abstract

The Video Interaction Project (VIP) is a healthcare-based intervention that provides real-time video-feedback of parent-child play and reading interactions to families with children aged 0 to 36 months. Although evidence from randomized controlled trials demonstrates improved early relational health, including responsive parenting, after three to five VIP visits, the minimal effective dose in real-world implementations is unknown. This study aimed to determine the minimal effective dose of VIP during a real-world implementation for changing responsive parenting behaviors. We performed a longitudinal prospective study of 183 dyads at a public hospital pediatric clinic. Responsive parenting behaviors were assessed with an observational checklist utilized as part of standard VIP practice at baseline and two follow-up VIP visits. Multilevel models adjusted for baseline sociodemographics (child's sex and age, and maternal education) and time between visits showed that responsive parenting behaviors during parent-child reading and play significantly increased after a single VIP visit (Cohen's d = 0.52, p < 0.05) with additional impact following completion of a second visit (cumulative for 2 visits: d = 0.76, p < 0.05). A single VIP visit is associated with increased responsive parenting behaviors. Findings support offering VIP widely, regardless of capacity to ensure attendance at multiple visits. This is the first study showing the minimal effective dose of the Video Interaction Project (VIP) for increasing responsive parenting behaviors. Responsive parenting behaviors increased by over 22% following a single VIP visit, with a cumulative increase of 37% following the second visit compared to baseline. Findings have important implications for implementation and scalability of pediatric-based preventive programs that support early relational health through activities such as reading and play.
